I thing Nortech builds an incredible product. The range of consumer they go after is amazing! Just look at what they're willing to build, almost anything. What they build also has a cool factor of 10! I went on a work trip last Summer and did a snorkeling trip on a large sail catamaran. A beautiful 30 something checked us in at the boarding of the boat and took our shoes. I went up to the Captain station to see who was going to Captain this impressive vessel upon boarding the boat. It was the the woman who checked us in. I asked if she was the Captain. She responded with yes I am. I asked where in the world she learned how to drive of a boat of this size. She told me she was from Norway and that's what they know. I fell in love immediately, go Nortech!

I had a 2010 40 Roadster - the tunnel delaminated from the transom about 3 feet forward. The foam core turned to powder. Called Nortech - they denied ever having that problem. Had an infusion repair done by a pro. When i went to sell the boat 2 people contacted me and said they had the same issue with their Nortech. The factory lied period. The only Cats i would consider are from builders doing would free infusion layups - like MTI, Doug Wright, DCB, ect.

The tunnel was 3 layers of glass 2 layers of foam core. Not solid glass.

I’ve seen quite a few MTI cats delaminate in the tunnel. Seen them come apart beneath cockpit area and at the transom. Pretty much every manufacturer has had boats delaminate.

We have some really nice stuff being built with high tech composite materials at this point but it sure is pricy. We have been using some refrigerated prepreg carbon on my project (cool stuff)-literally.

Maybe they used PU foam instead of PVC?
PVC is difficult to turn into powder.
PU is harder, but crumbles and delaminates faster than PVC.
